Description

Die Erfindung betrifft eine Transfereinrichtung mit den Merkmalen des Oberbegriffes des Patentanspruches 1.The invention relates to a transfer device the features of the preamble of claim 1.

Bei Pressenanlagen mit mehreren Pressenstufen, die entlang eines Teiledurchflußweges hintereinander angeordnet sind, werden Transfereinrichtungen vorgesehen, die die entsprechenden Blechteile aus den Pressenstufen entnehmen und taktweise der jeweils folgenden Pressenstufe zuführen. Zwischen den einzelnen Pressenstufen sind meist Zwischenablagen vorgesehen, auf denen die zu transportierenden Werkstücke temporär abgelegt werden können, was es ermöglicht, die Weite des Transferschrittes zu verringern. Zur Durchführung des Transferes wird eine Transfereinrichtung verwendet, die die Werkstücke bei geöffnetem Werkzeug ergreift und in einer Transferbewegung, bei der sich eine Hebebewegung einer horizontalen Transferbewegung überlagert, aus dem Werkzeug herausführt bzw. in dieses einsetzt, wobei sich der Transferbewegung eine vertikale Senk- oder Ablegbewegung überlagert.For press systems with several press stages, the arranged one behind the other along a parts flow path transfer facilities are provided that the corresponding sheet metal parts from the press stages remove and intermittently from the following press stage respectively. Are between the individual press stages mostly clipboards provided on which to be transported Workpieces can be temporarily stored, which allows the width of the transfer step to increase reduce. To carry out the transfer, a Used transfer device that the workpieces grabs open tool and in a transfer movement, in which there is a lifting movement of a horizontal Transfer movement overlaid, leads out of the tool or sets in this, with the transfer movement a vertical lowering or depositing movement is superimposed.

Insbesondere bei kompliziert gestalteten Werkstücken und/oder Werkstücken, die schräg, das heißt von einer Horizontalebene abweichend, in Werkzeuge einzusetzen sind, kann es erforderlich sein, das Werkstück beim Transfer, bspw. während des Herausführens oder des Einführens aus dem bzw. in das Werkzeug, um eine Querachse zu schwenken. Bei entsprechenden Werkzeug- und Werkstückformen kann dies notwendig werden, um eine Kollision zwischen Blechteil und Werkzeug während der Umsetzbewegung zu vermeiden. Die erste Bearbeitungsstufe von Pressenanlagen, gegebenenfalls auch eine nachfolgende Bearbeitungsstufe, ist als Ziehstufe ausgelegt. Die weitere Bearbeitung verlangt gegebenenfalls eine Schräglage des Blechteiles im Unterwerkzeug. Zum einen kann z. Bsp. wegen der hohen Hubzahlen der Aushebehub nicht beliebig groß gewählt werden, zum anderen ist es erforderlich, durch Tiefziehen abgewinkelte, tiefgestellte Ziehflächen frei oberhalb der Form des Unterwerkzeuges vorbeizuführen.Especially for workpieces with complicated designs and / or workpieces that are at an angle, that is from one Different horizontal plane, to be used in tools are, it may be necessary to hold the workpiece Transfer, for example, during the removal or insertion out of or into the tool about a transverse axis to pan. With appropriate tool and workpiece shapes this may become necessary to avoid a collision between sheet metal part and tool during the transfer movement to avoid. The first processing stage of press systems, possibly also a subsequent processing stage, is designed as a drawing stage. The further one Processing may require an inclined position of the Sheet metal part in the lower tool. For one, z. E.g. because of the high number of strokes the lifting stroke is not arbitrary be chosen large, on the other hand it is necessary angled, lowered drawing surfaces by deep drawing pass freely above the shape of the lower tool.

Eine entsprechende Umsetzeinrichtung ist aus der EP-A-0 499 901 bekannt geworden. Zu der Umsetzeinrichtung gehören zwei sich in Transferrichtung erstreckende, rechts- und linksseitig neben den Werkzeugen der Pressenstufen angeordnete Führungsschienen, auf denen Laufwagen gelagert sind. Die Führungsschienen sind mit einer Hebe- und Senkeinheit verbunden, um eine gezielte Horizontalbewegung auszuführen. Die Laufwagen stehen mit einer Transferantriebseinheit in Verbindung, um gezielt entlang der Laufschienen bewegt werden zu können. Jeweils zwischen zwei Laufwagen ist eine Quertraverse angeordnet, die endseitig drehbar an den Laufwagen gelagert ist. Als Greifermittel zum Ergreifen und Halten von Blechteilen trägt die Quertraverse eine Saugerspinne, die eine Anzahl mit Vakuum beaufschlagbarer Saugfüße aufweist. Um die Saugerspinnen um eine Querachse schwenken zu können, ist die betreffende Quertraverse endseitig über eine Kupplung mit einem Schwenkhebel verbunden, der mittels eines an dem Laufwagen vorgesehenen Antriebszylinders verschwenkbar ist.A corresponding conversion device is from the EP-A-0 499 901 has become known. To the transfer device include two that extend in the transfer direction, right and left side next to the tools of the press stages arranged guide rails on which carriages are stored. The guide rails are with a lifting and Lowering unit connected to a targeted horizontal movement to execute. The carriages stand with a transfer drive unit in conjunction to target along the To be able to move rails. Between each a crossbeam is arranged on two carriages is rotatably supported on the end of the carriage. As Gripper means for gripping and holding sheet metal parts the cross-beam carries a suction spider that has a number has vacuum feet that can be acted upon by vacuum. To the Vacuum spider can be pivoted about a transverse axis the crossbar in question at the end via a coupling connected to a swivel lever, which by means of a the drive cylinder provided pivotable is.

Um die Transfereinrichtung in ihrer Verwendbarkeit nicht auf Anwendungsfälle zu beschränken, bei denen in nur einer oder in wenigen Stationen Drehbewegungen der Werkstücke erforderlich sind, müssen alle Laufwagen mit entsprechenden Dreheinheiten ausgerüstet werden. Dies verkompliziert die Konstruktion und erhöht das Gewicht der Transfereinrichtung und insbesondere der Laufwagen, was entsprechend höhere aufzubringende Beschleunigungs- und Bremskräfte bedingt und energetisch nachteilig ist. Darüber hinaus erfordert die Konstruktion einen beachtlichen Bauraum, der die zulässige Hubhöhe des Transfersystemes (der Quertraversen) reduziert.To the transfer facility in its usability not to be limited to use cases in which only one or in a few stations rotary movements of the Workpieces are required, all carriages must be with appropriate rotating units. This complicates the construction and increases the weight the transfer device and in particular the carriage, which correspondingly higher acceleration and Braking forces are conditional and energetically disadvantageous. In addition, the construction requires a considerable amount Installation space, which is the permissible lifting height of the transfer system (the crossbar) reduced.

Eine Transfereinrichtung soll idealerweise so gestaltet sein, daß sie eine Vielzahl von Werkstücken handhaben kann, so daß sie auch für zukünftige, im einzelnen nicht absehbare Aufgaben einrichtbar ist.A transfer device should ideally be designed in this way be a variety of workpieces can handle, so that they can be used for future, in detail unforeseeable tasks can be set up.

Aus der JP 62-142431 ist eine Transfereinrichtung bekannt, bei der ein eine Saugerspinne tragender Träger im ganzen drehbar an einer Dreheinheit gelagert ist. Die Dreheinheit ist an einem vertikal auf und ab sowie horizontal bewegbaren Träger gehalten.JP 62-142431 is a transfer device known in which a carrier carrying a suction spider is rotatably mounted on a rotating unit. The Turning unit is up and down vertically and horizontally movable carrier held.

Soll eine entsprechende Transfereinrichtung mehrere solcher Querträger aufweisen, ist an jeder Querträgerposition eine Dreheinheit erforderlich, unabhängig davon, ob für den konkreten Einsatzfall und an der jeweiligen Position tatsächlich eine Schwenkbewegung der Saugerspinne benötigt wird. Dies schlägt sich im konstruktiven Aufwand und im Gewicht der Transfereinrichtung nieder.Should a corresponding transfer device be several have such crossmember is at each crossmember position a turntable is required regardless of whether for the specific application and on the respective Position actually pivots the suction spider is needed. This is reflected in the constructive Effort and weight of the transfer device.

Davon ausgehend ist es Aufgabe der Erfindung, eine Transfereinrichtung zu schaffen, die eine hohe Variabilität ermöglicht.Based on this, it is an object of the invention to To create transfer device that has a high variability enables.

Diese Aufgabe wird mit einer Transfereinrichtung gelöst, die die Merkmale des Patentanspruches 1 aufweist:This task is done with a transfer facility solved, which has the features of claim 1:

Die an sich starr ausgebildeten Quertraversen tragen jeweils drehbar an ihnen gelagerte Saugerspinnen. Außerdem trägt die Quertraverse das Antriebsmittel, bspw. einen Getriebemotor, hydraulische oder pneumatische Antriebe, die die Greifermittel bedarfsweise schwenken. Dies schafft die Möglichkeit, Quertraversen mit schwenkbaren Greifermitteln an Positionen der Transfereinrichtung vorzusehen, die baulich mit solchen Positionen übereinstimmen, die für Quertraversen mit unverschwenkbaren Greifermitteln ausgebildet sind. Die endseitige Aufhängung der Quertraversen ist, unabhängig davon, ob die betreffende Quertraverse schwenkbare Greifermittel trägt oder nicht, einheitlich ausgebildet. Es sind keine auf die Enden der Quertraversen einwirkende Dreheinheiten erforderlich, die an den Trag- und Führungsmitteln, bspw. auf Laufschienen gelagerten Laufwagen, fest vorzusehen wären. Dies ermöglicht den schnellen Wechsel von Quertraversen mit drehbaren Greifermitteln gegen Quertraversen mit unverschwenkbaren Greifermitteln und umgekehrt. Der konstruktive bauliche und wirtschaftliche Aufwand wird somit für jeden Einsatzfall auf das jeweils erforderliche Maß reduziert. Gleichzeitig bietet die Transfereinrichtung ein hohes Maß an Variabilität und ermöglicht eine schnelle und problemlose Anpassung an unterschiedliche, auch zukünftige Transferaufgaben. Wear the crossbars, which are rigid in themselves suction spiders rotatably mounted on them. Furthermore the crossmember carries the drive means, e.g. a geared motor, hydraulic or pneumatic Drives that swivel the gripper means as required. This creates the possibility of cross beams with swiveling Gripper means at positions of the transfer device to be provided structurally with such positions match that for crossbeams with non-pivoting Gripper means are formed. The end Suspension of the crossbeams is independent of whether the relevant crossbar swiveling gripper means wears or not, uniformly trained. There are not any rotating units acting on the ends of the crossbeams required on the load-bearing and guiding means, e.g. Carriages mounted on running rails, to be provided firmly would be. This enables the quick change of crossbeams with rotatable gripper means against cross beams with non-swiveling gripper means and vice versa. Of the constructive structural and economic effort thus for each application to the required Dimension reduced. At the same time, the transfer facility offers a high degree of variability and enables one quick and easy adaptation to different, also future transfer tasks.

Nachdem auf die Greifermittel einwirkende Antriebsmittel lediglich an solchen Positionen bzw. Quertraversen vorzusehen sind, an denen sie tatsächlich erforderlich sind, ist die zu beschleunigende und abzubremsende Masse der Transfereinrichtung nicht durch unnötige, mitzubewegende Antriebseinrichtungen erhöht. Dies ermöglicht einen schnellen Transfer bzw. eine Senkung der Antriebs-/Bremsleistung.After driving means acting on the gripper means only at such positions or cross members are to be provided where they are actually required is the mass to be accelerated and braked the transfer device not by unnecessary, to be moved Drive devices increased. This enables one fast transfer or a reduction in drive / braking power.

Die schwenkbare Lagerung der Greifermittel an der Quertraverse und die Zuordnung eines von der Quertraverse getragenen Antriebsmittels zu jedem Greifermittel schafft die Basis dafür, daß das an ein und derselben Quertraverse vorgesehene Greifermittel in unterschiedlich zu steuernde bzw. zu schwenkende Greifereinheiten unterteilt wird. Bspw. können an einer Quertraverse eine erste und eine zweite Saugerspinne vorgesehen werden, von denen lediglich eine verschwenkt wird oder die unterschiedlich verschwenkt werden. Damit können unterschiedlich zu verschwenkende Blechteile, die nebeneinander durch die Pressenstufen zu transportieren sind, gehandhabt werden. Solches kann erforderlich werden, wenn aus einer Platine zwei getrennte Blechteile entstehen, die unterschiedlich gestaltet sind. Die Vielseitigkeit der erfindungsgemäßen Transfereinrichtung ermöglicht es hier sogar, ein Blechteil, das als Ausschnitt zur Ausbildung einer großen Öffnung in einem anderen Blechteil von diesem getrennt worden ist, mit diesem synchron weiter zu transportieren und zu einem eigenen Teil zu formen. Es kann dabei mit einer eigenen Saugerspinne, die auf der gleichen Quertraverse sitzt wie die Saugerspinne für das umgebende, größere Teil, gehalten und transportiert und auch in andere Kippwinkel überführt werden.The swiveling storage of the gripper means on the Crossbeam and the assignment of one of the crossbeam creates carried drive means to each gripper means the basis for that on the same crossbar provided gripper means in different controlling or pivoting gripper units divided becomes. E.g. can a first and a second suction spider can be provided, one of which only one is pivoted or the different be pivoted. This can be different pivoting sheet metal parts that are juxtaposed by the Press stages to be transported are handled. Such may be necessary if from a circuit board two separate sheet metal parts are created that are different are designed. The versatility of the invention Transfer device even enables a sheet metal part that as a cutout for training a large one Opening in another sheet metal part separated from this has been transported with it synchronously and to shape it in its own part. It can be done with its own suction spider on the same cross-beam sits like the suction spider for the surrounding, larger part, kept and transported and also in other tilt angles are transferred.

Eine Kupplungsanordnung zwischen der Quertraverse und den Greifermitteln bzw. einer aus Greifermitteln, Lagereinrichtung und Antriebsmitteln gebildeten Greifereinheit kann bedarfsweise das Lösen der Greifereinheit von den Quertraversen ermöglichen, so daß die Quertraversen für einen jeweiligen Einsatzfall umrüstbar sind. Insbesondere können auch schwenkbare gegen nichtschwenkbare Greifermittel/Einheiten ausgetauscht werden.A coupling arrangement between the crossbar and the gripper means or one of gripper means, Bearing device and drive means formed gripper unit can, if necessary, loosen the gripper unit of the crossbars so that the crossbars can be converted for a particular application. In particular, can also be pivoted against non-pivotable Gripper means / units can be exchanged.

Die Drehachse der Greifermittel liegt vorzugsweise innerhalb der Quertraverse, wobei der Schwerpunkt des Werkstückes unterhalb der Quertraverse liegt. Dadurch entsteht kein nennenswertes, auf die Antriebsmittel einwirkendes Drehmoment durch die Gewichtskraft des Werkstückes.The axis of rotation of the gripper means is preferably within the crossbar, with the focus of the Workpiece lies below the crossbar. Thereby no noteworthy arises on the drive means acting torque by the weight of the Workpiece.

Bei einer manuell auf einfache Weise umrüstbaren Bauform gehört zu der Lagereinrichtung wenigstens eine geteilte Lagereinheit, die zwei bogenförmige Führungsflächen aufweist, auf denen die Greifermittel durch Rollen gelagert sind, wobei zur Koppelung mit einem als Antriebsmittel dienenden Getriebemotor ein Zahnradsegment dient, das auch als gebogene Zahnstange aufgefaßt werden kann. Diese Bauform ermöglicht eine besonders geringe Bauhöhe der schwenkbaren Greifereinheit, die nicht oder kaum größer ist als die einer unverschwenkbaren. Dadurch wird der zulässige Vertikalhub der Transfereinrichtung nicht eingeschränkt.With a manually convertible in a simple way Design belongs to the storage facility at least one split bearing unit, the two arcuate guide surfaces has on which the gripper means by Rollers are stored, being for coupling with a as Gear motor serving drive means a gear segment serves that can also be understood as a curved rack can. This design enables a particularly small one Height of the swiveling gripper unit, which is not or is hardly larger than that of an immovable. Thereby becomes the permissible vertical stroke of the transfer device not limited.

Beschreibungdescription

In Fig. 1 ist eine Pressenanlage 1 veranschaulicht, die eine Folge von Pressenstationen aufweist, von denen zwei Pressenstationen 3, 4 veranschaulicht sind. Zu jeder Pressenstation 3, 4 gehört ein Schiebetisch 5, 6 zur Aufnahme jeweils eines Unterwerkzeuges 7, 8, dem jeweils ein an einem Stößel gehaltenes Oberwerkzeug 9, 10 zugeordnet ist. Die Oberwerkzeuge 9, 10 werden von den Stößeln im Gleichtakt in Richtung der Pfeile 11, 12 taktweise auf und ab bewegt. In den Pressenstationen 3, 4 werden Blechteile 14, 15 stufenweise bearbeitet. Zur bedarfsweisen Ablage eines weiteren Blechteiles 16 zwischen den Pressenstationen 3, 4 kann auf halbem Wege zwischen beiden Schiebetischen 5, 6 eine Zwischenablage 18 angeordnet sein. Diese weist bedarfsweise in mehreren Achsen einstellbare Schablonen auf, um so das Blechteil bei der Ablage aufzunehmen und bedarfsweise für den Weitertransport in Höhe- und Schräglage auszurichten.1 shows a press system 1, which has a series of press stations, of which two press stations 3, 4 are illustrated. For everyone Press station 3, 4 includes a sliding table 5, 6 Inclusion of a lower tool 7, 8, each an upper tool 9, 10 held on a tappet is assigned is. The upper tools 9, 10 are of the Tappets in the direction of arrows 11, 12 moved up and down in cycles. In the press stations 3, 4 sheet metal parts 14, 15 are processed in stages. For if necessary, a further sheet metal part 16 between the press stations 3, 4 can be halfway there a clipboard between the two sliding tables 5, 6 18 may be arranged. If necessary, this has several Axes adjustable stencils around the sheet metal part when filing and if necessary for the Align further transport in height and inclined position.

Die Blechteile 14, 15, 16 werden entlang einer Transferkurve 21, 22 von der Pressenstation 3 zu der Zwischenablage 18 und von dieser zu der Pressenstation 4 transportiert oder direkt von Pressenstation 3 zu Pressenstation 4 transportiert. Die Transferkurven 21, 22 werden durch vertikale Heb-Senk-Bewegungen (V in Fig. 2) gebildet, denen ein horizontaler Transporthub (H in Fig. 2) überlagert ist. Es kann dabei erforderlich sein, daß das Blechteil 14, 15 oder 16 schon in der Aushebebewegung aus dem Unterwerkzeug 7, 8 oder bei der Abnahme von der Zwischenablage 18 in eine solche Kipplage zu drehen ist, daß tiefgezogene Kanten beim Transport nicht von dem jeweiligen Unterwerkzeug 7, 8 oder der Aufnahme der Zwischenablage 18 behindert werden. The sheet metal parts 14, 15, 16 are along a Transfer curve 21, 22 from the press station 3 to the Clipboard 18 and from this to the press station 4 transported or directly from press station 3 to press station 4 transported. The transfer curves 21, 22 are achieved by vertical lifting-lowering movements (V in Fig. 2) formed, which a horizontal transport stroke (H in Fig. 2) is superimposed. It may be necessary that the sheet metal part 14, 15 or 16 already in the lifting movement from the lower tool 7, 8 or when removing from the Clipboard 18 is to be turned into such a tilted position, that deep-drawn edges are not separated from the respective lower tool 7, 8 or the inclusion of the Clipboard 18 are hindered.

Zum Transfer der Blechteile 14, 15, 16 sowie gegebenenfalls zum Verschwenken derselben dient eine Transfereinrichtung 23, von der in Fig. 2 ein Teilausschnitt aufs äußerste schematisiert dargestellt ist. Zu dieser gehören zwei im Abstand parallel zueinander sowie parallel zu einer Transportrichtung T angeordnete Hubbalken oder Laufschienen 24, 25, auf denen jeweils Laufwagen 26, 27, 28, 29, 30, 31 in Transportrichtung T verfahrbar gelagert sind, die jeweils über lediglich schematisch angedeutete Gestänge 32 angetrieben sind. Jeweils paarweise zwischen zwei Laufwagen 26, 27; 28, 29; 30, 31 ist eine Quertraverse 33, 34, 35 gehalten, die mit ihren Enden lösbar mit dem jeweiligen Laufwagen 26, 27, 28, 29, 30, 31 verbunden ist. Zur Verbindung dienen Kupplungsmittel, wie sie bspw. aus Fig. 3 hervorgehen.To transfer the sheet metal parts 14, 15, 16 and, if necessary a transfer device serves to pivot the same 23, a partial section of which is shown in FIG outermost is shown schematically. Belong to this two parallel to each other and parallel to each other a transport direction T arranged walking beam or Running rails 24, 25, on which carriages 26, 27, 28, 29, 30, 31 movably supported in the transport direction T. are, each of which is only indicated schematically Linkage 32 are driven. Each in pairs between two carriages 26, 27; 28, 29; 30, 31 is a crossbar 33, 34, 35 held with their ends releasably the respective carriage 26, 27, 28, 29, 30, 31 connected is. Coupling means such as those used, for example, emerge from Fig. 3.

Jede Quertraverse 33, 34, 35 trägt als Greifermittel für die Blechteile 14, 15, 16 Saugerspinnen 36, 37, 38, wobei wenigstens die an der Quertraverse 34 gehaltenen Saugerspinnen 37 drehbar an der Quertraverse 34 gelagert sind.Each crossbar 33, 34, 35 carries as a gripper means for sheet metal parts 14, 15, 16 suction spiders 36, 37, 38, at least those held on the cross-beam 34 Suction spiders 37 rotatably mounted on the crossbar 34 are.

Wie aus Fig. 3 hervorgeht, weist die Quertraverse 34 einen durchgehenden, starren, aus einem Kastenprofil ausgebildeten Träger auf, der an seinen beiden Enden mit Kupplungshälften 41, 42 zur Verbindung mit den Laufwagen 28, 29 versehen ist. Der Träger trägt zwei Saugereinheiten 37a, 37b, die zueinander spiegelsymmetrisch ausgebildet sind. Die folgende, sich auf die Saugereinheit 37a beziehende Beschreibung gilt somit entsprechend für die Saugereinheit 37b.As can be seen from FIG. 3, the crossbar 34 a continuous, rigid, from a box profile trained carrier on with at both ends Coupling halves 41, 42 for connection to the carriage 28, 29 is provided. The carrier carries two suction units 37a, 37b, which are mirror-symmetrical to one another are. The following, referring to the suction unit 37a relevant description applies accordingly to the Suction unit 37b.

Zu der Saugereinheit 37a gehören mehrere, über Arme 44a mit einem Gestell 45a verbundene Sauger 46a. Das Gestell 45a ist über eine bspw. aus den Fig. 4 und 5 ersichtliche Lagereinrichtung 47a an einer Halterung 48a gelagert, die an entsprechende, von der Quertraverse 34 getragene, im Abstand zueinander angeordnete Sockel 49a, 50a ankuppelbar ist.The suction unit 37a includes a number of arms 44a suction device 46a connected to a frame 45a. The Frame 45a is, for example, from FIGS. 4 and 5 apparent bearing device 47a on a bracket 48a mounted on the corresponding, from the crossbar 34th supported bases 49a spaced from each other, 50a can be coupled.

Die Halterung 48a umfaßt die Quertraverse 34, wie Fig. 5 zeigt, dreiseitig und ist nach unten offen. Gleiches gilt für den mit dem Sockel 50a verbundenen Teil 48a' der Halterung.The bracket 48a includes the crossbar 34, such as Fig. 5 shows three sides and is open at the bottom. Same thing applies to the part connected to the base 50a 48a 'of the bracket.

An der Halterung 48a, 48a' sind als Kupplungsgegenstücke dienende, spatenförmige Fortsätze als Einführhilfe ausgebildet sowie Kupplungsbolzen vorhanden, die von den Sockeln 49a, 50a aufgenommen werden und mit diesen eine lösbare Kupplungsanordnung bilden. Sicherungsmittel verhindern ein unbeabsichtigtes Lösen der Kupplungsanordnung.On the bracket 48a, 48a 'are as coupling counterparts serving, spade-shaped extensions as an insertion aid trained and coupling bolts available by the Sockets 49a, 50a are included and with these one Form releasable clutch assembly. Security means prevent unintentional loosening of the coupling arrangement.

Die Lagereinrichtung 47a wird durch an dem Halter 48a, 48a' ausgebildete, bogenförmige Flächen 52a, 53a gebildet, die jeweils paarweise auf einem gemeinsamen Kreis liegen, dessen Mittelpunkt M dem Mittelpunkt der Quertraverse 34 entspricht (Fig. 5). Das nach unten ebenfalls offene Gestell 45a ist bspw. durch insgesamt vier Rollen 56a, 57a, 58a, 59a auf den bogenförmigen Flächen 52a, 53a gelagert. Als Alternative zu dieser Rollenlagerung wäre bspw. auch eine bogenförmige Profilschienenführung denkbar.The bearing device 47a is on the holder 48a, 48a 'formed arcuate surfaces 52a, 53a formed, each in pairs on a common Circle lie whose center M is the center of the Crossbar 34 corresponds (Fig. 5). That down likewise open frame 45a is, for example, by total four rollers 56a, 57a, 58a, 59a on the arcuate Surfaces 52a, 53a stored. As an alternative to this Roller bearings would also be, for example, an arcuate profile rail guide conceivable.

Ein mit dem Gestell 45a verbundenes, seitlich neben den Rollen 58a, 59a angeordnetes Zahnradsegment 61a dient zur Koppelung des Gestelles 45a mit einem Servomotor 62a, der neben der Halterung 48a in gleicher Höhe wie die Quertraverse 34 angeordnet ist. Der Servomotor 62a ist über ein hochuntersetzendes, sogenanntes Harmonic-Drive-Getriebe 63a mit einem endseitig eine Verzahnung tragenden Hebel 64 verbunden, der auch als Zahnradsegment aufgefaßt werden kann und dessen Verzahnung mit dem Zahnradsegment 61a kämmt. Seine Drehachse ist dabei parallel zu der Drehachse des Gestelles 45a ausgerichtet.A connected to the frame 45a, next to the side Gear segment 61a arranged on the rollers 58a, 59a is used for coupling the frame 45a to a servo motor 62a, the next to the bracket 48a at the same height as that Crossbar 34 is arranged. The servo motor 62a is via a high-reduction, so-called harmonic drive gear 63a with a toothing at the end Lever 64 connected, which is also a gear segment can be understood and its interlocking with the Gear segment 61a meshes. His axis of rotation is there aligned parallel to the axis of rotation of the frame 45a.

Die insoweit beschriebene Pressenanlage 1 und insbesondere die Transfereinrichtung 23 arbeiten wie folgt:The press system 1 described so far and in particular the transfer device 23 operate as follows:

Entsprechend dem Takt der Pressenstößel der in Fig. 1 veranschaulichten Pressenstationen 3, 4 werden mittels entsprechender Antriebseinheiten A die Laufschienen 24, 25 in Vertikalrichtung V und die Laufwagen 26, 27, 28, 29, 30, 31 in Horizontalrichtung H so bewegt, daß die Quertraversen 33, 34, 35 die Transferkurven 21, 22 durchlaufen. Die im Rücklaufhub in unterschiedlichen Wegstellungen dargestellten Quertraversen 34, 35 können dabei so angesteuert werden, daß die Saugerspinnen 37 (37a, 37b) während der Horizontal- und/oder Vertikalbewegung der Quertraverse 34 um diese schwenken. Die Saugerspinnen 37 können so in eine Schräglage positioniert werden, in der sie an das von der Zwischenablage 18 in Kipplage gehaltene Blechteil 16 ansetzbar sind. Bei der Rücksetzbewegung bei der Quertraverse 34 werden die Saugerspinnen 37 in diese Position gedreht. Damit wird das Blechteil 16 auf der Transferkurve 22 störungsfrei in das Unterwerkzeug 8 gelegt. Auch beim Einführen des Blechteiles 16 in die Pressenstation 4 oder beim Entnehmen aus Pressenstation 3 kann es mittels Verschwenkung der Saugerspinnen 37 bedarfsweise in unterschiedliche Kipplagen gebracht werden.According to the cycle of the press rams in Fig. 1, press stations 3, 4 are illustrated by means of corresponding drive units A the rails 24, 25 in the vertical direction V and the carriages 26, 27, 28, 29, 30, 31 moved in the horizontal direction H so that the Cross members 33, 34, 35 pass through the transfer curves 21, 22. The one in the return stroke in different positions shown cross members 34, 35 can be so controlled that the suction spiders 37 (37a, 37b) during the horizontal and / or vertical movement of the Swivel crossbar 34 around this. The suction spiders 37 can be positioned in an inclined position in the them to that held by the clipboard 18 in a tilted position Sheet metal part 16 are attachable. With the reset movement at the cross member 34, the suction spiders 37 in rotated this position. So that the sheet metal part 16 the transfer curve 22 into the lower tool 8 without interference placed. Even when inserting the sheet metal part 16 in the Press station 4 or when removing from press station 3 can if necessary by pivoting the suction spiders 37 be brought into different tilt positions.

Die angedeuteten Drehverstellungen der Quertraversen sind lediglich beispielhaft. Durch die freie Ansteuerbarkeit der Servomotoren 62 und beliebiges Auswechseln der Quertraversen 33, 35 gegen solche, die jeweils eine oder mehrere Schwenkeinheit(en) tragen, sind vielfältige Kombinationen möglich. Anstelle der Schwenkeinheiten können an den Sockeln 49, 50 auch unverschwenkbare Saugerspinnen angekuppelt werden, die in Horizontalrichtung oder in einer geneigten Richtung orientiert sind. Die in Fig. 3 veranschaulichten Sockel 49a, 50a bilden mit entsprechenden Fortsätzen der Halterung 48a, 48a' eine Kupplungsanordnung, die mit einer nicht weiter dargestellten Verriegelungseinrichtung zur Arretierung versehen ist. Entriegelt wird die betreffende Kupplungsanordnung durch eine kurzhubige, axial zu der Quertraverse 34 gerichtete Bewegung und Wegschwenken des Verriegelungsbolzens, wonach die Saugereinheit 37a, 37b abnehmbar ist. Bedarfsweise kann die Kupplungsanordnung auch durch anderweitige Verbindungsmittel ersetzt sein, so daß die betreffende Saugereinheit 37a, 37a fest mit der jeweiligen Quertraverse 34 (33, 35) verbunden ist.The indicated rotary adjustments of the crossbeams are only exemplary. Due to the free controllability the servomotors 62 and any replacement the cross members 33, 35 against those, each one or carry multiple swivel unit (s) are diverse Combinations possible. Instead of the swivel units can also non-swiveling suction spiders on the bases 49, 50 be coupled in the horizontal direction or are oriented in an inclined direction. In the Fig. 3 illustrated base 49a, 50a form with corresponding extensions of the holder 48a, 48a ' Coupling arrangement with a not shown Provide locking device for locking is. The relevant clutch arrangement is unlocked due to a short stroke, axially to the crossbar 34 directed movement and pivoting away of the locking bolt, after which the suction unit 37a, 37b is removable. If necessary, the clutch arrangement also be replaced by other lanyards, so that the relevant suction unit 37a, 37a with the respective crossbar 34 (33, 35) is connected.

Eine Transfereinrichtung 23 für eine Pressenanlage 1 weist Quertraversen 33, 34, 35 auf, an denen jeweils wenigstens eine Saugereinheit 37a gehalten ist, die um die Quertraverse 34 schwenkbar an dieser gelagert ist. Die Saugereinheit 37a weist einen vorzugsweise elektrischen Antrieb auf, mittels dessen die Schwenkbewegung auf die zu durchlaufende Transferkurve (Horizontal- und Vertikalbewegung) abstimmbar ist. Bedarfsweise können auf einer Quertraverse zwei oder mehr Saugereinheiten 37a, 37b angeordnet werden, die unabhängig voneinander verschwenkbar sind. Ein Nachrüsten und Umrüsten von vorhandenen Quertraversen ist durch Ersatz von bislang verwendeten unverschwenkbaren Saugereinheiten durch verschwenkbare möglich. Sonstige Änderungen an der mechanischen Struktur der Transfereinrichtung 23 sind nicht erforderlich.A transfer device 23 for a press system 1 has cross members 33, 34, 35, on each of which at least one suction unit 37a is held around the crossbar 34 is pivotally mounted on this. The suction unit 37a preferably has an electrical one Drive on, by means of which the swivel movement the transfer curve to be traversed (horizontal and Vertical movement) is tunable. If necessary, can a crossbar two or more suction units 37a, 37b are arranged, which can be pivoted independently of one another are. Retrofitting and retrofitting of existing ones Crossbeam is used by replacement of previously non-swiveling suction units by swiveling possible. Other changes to the mechanical Structure of the transfer device 23 are not required.
